Web Applications Vulnerabilities- A Survey

Web applications are prone to attack. With the development of new tools and technologies, attackers gets success to attack web applications although enormous security controls are deployed. Attackers use the web application vulnerabilities to attack the web applications. The reason of attack may be any either to defame the web application or owner of the web application, steal the credentials, black mailing or financial gain. Although percentage of frequency of attacks are reducing but still attackers are exploiting vulnerabilities to gain access of control of web applications or adversely affecting the web applications and/or their clients. This paper is a survey of various web application vulnerabilities, their sources of attacks, most prevailing types of vulnerabilities and their impact domains. Considering all these aspects, researchers further my work on countermeasures of such vulnerabilities so that impact of web application vulnerabilities can be reduces at the maximum extent.
